21. Reading A GPS 3 Formats hemisphere degrees, minutes, seconds hemisphere degrees, minutes hemisphere degrees hemisphere degrees, minutes, seconds 33 07 03N 87 07 02 W 33 o 07 03N 87 o 07 02 W hemisphere degrees, minutes 33 07 043N 87 07 02W 33 o 07 043N 87 o 07 02W hemisphere degrees 33 11.735N 87 11.718W 33 11.735 o N 87 11.718 o W

23. Conversions 1035.75 miles between latitude lines 69.05 miles between 1 degree of latitude 1.15 miles between minutes.019 miles between seconds; which equals100 feet and 3.5 inches.

24. However its a Sliding Scale At 38 degrees North latitude one degree of latitude equals approximately 364,000 ft (69 miles), one minute equals 6068 ft (1.15 miles), one-second equals 101 ft. one-degree of longitude equals 288,200 ft (54.6 miles), one minute equals 4800 ft (0.91 mile), and one second equals 80 ft.

25. I Need You To Cosign Cosine Open the calculator in Windows (Start Programs Accessories Calculator) Click on View & Scientific Choose Decimal and Degrees Type in known latitude in the following format 11735 as opposed to 33 11.735) degrees. degrees (33.11735 as opposed to 33 11.735) Click the Cosine Key (cos) Multiply answer by 69 The answer is the miles between longitudes at that latitude
